'1 '0 ((ZZ whom it may concern Be it known that I, OLIVIA IV. Tucnnu, a citizen of the United States, residing at East Providence, in the county of Providence, State of Rhode Island, have invented a new and useful Improvement in Portable ater- Heaters, of which the following is a specification.

My invention relates to a device for heating water for use in bath tubs, basins, sinks, wash tubs, and the like; and the object in view is to provide means, more particularly adapted. for domestic use during the summer season, whereby hot water may be readily had at much lesser expcnsc,-than in the case where a boilerfurnace fire has to be started to furnish the hot water supply.

In the accompanying sheet of drawings, Figure 1 represents a transverse section of my improved water heating device, taken on line of Fig. 2, and, Fig. 9 is a central longitudinal section of the device, taken on line y .;z of Fig. 1.

Like reference characters parts.

My improved water heater is in the form of an elongated horizontal cylinder (Z having an inwardly extending annular flange at its front end, as at b, and its rear end closed, as at o, and within said cylinder and concentric thereto are three cylindrical walls (Z, (Z, (Z, arranged in close proximity to each other and to the outer annular wall of cylinder a and which are integral of the front and rear ends Z) and 0, in order to provide three separate thin annular chambers e, f, g surrounding each other; the outer chamber (2 to receive a circulation of cold water; the next or middle chamber f to receive a circulation of warm water, and the inner chamber 9 to receive a circulation of hot water.

On one side of the cylinder (4 is made fast a pipe 7L which is in open comnuinication with the cold water chamber 0, and said pipe curves upwardly and terminates with an integral outwardly extending annular flange 7?. On the flange portion of the pipe 72 is mounted a coupling Z, as a whole, consisting of a vertical tube 2''- having at one end an enlarged portion which is provided with a circular recess Z to receive the flange /iof said pipe h, and an operating lever i having an integral head i which surrounds and is made fast to said tube Z The tube 2' is split longitudinally throughout its length in indicate like order to permit its enlarged portion to inclose the flange 71 of the pipe 71, the fast h ad of the lever '2 keeps each half of said tube in place, and the upper portion of each half of said tube is exteriorly screwthreaded, as at 7"", to engage the threaded opening of a cold water faucet j. Thus, when the coupling is united to the faucet the pipe 7L and coupling '5 act to support the heater, and at the same time the flange-pipe Zz forms a pivot to accommodate the heater to be swung around to the position desired for discharging its hot water into the bath tub or other receptacle.

The water chambers 0, f, are divided by cross partitions which extend between the front and rear ends Z) and 0 of the cylinder a; one partition being located in the cold water chamber 0 and at a point near to and below the inlet Z1, as at c in Fig. 1; one partition being located in the warm water chamber f and at a point near to and below said partition 6 as at I, and one partition being located in the hot water chamber 1 at the opposite side of and below the axis of the cylinder a, as at in said figure.

A discharge pipe in communicates with the hot water chamber g, at a point above its partition g, and said pipe curves downwardly from the outside of the cylinder (1.

A bracket Z made fast to the lower part of the front end of the heater, and said bracket has a fork-shaped upper portion Z, as indicated by dotted lines in Fig. l, for a Bunsen type of burner m to rest between and A in such )osition that its blue flame will be directed centrally of and within the opening a left by the inner wall (Z of the heater.

In operation the water passes from the inlet it, up and around the chamber 0 and, through anopening 0 formed in the outer circular wall (Z, thence up and around the chamber j and through another opening 0- formed in the middle circular wall (Z, thence around the inner chamber and out through the discharge Z0.

hen hot water is required the ordinary flexible tube connection from the burner m is attached to a gas cock or point of gas supply. The burner is then ignited and the volume of water in circulation in the chamber 57 is closest to the intense heat from the flame this body of water is always kept the hottest, over that in circulation through the chambers c and The hot water chamber 9 is of larger capacity than the chamber and the outer chamber 0 of smaller capacity than said middle chamber, and this difference in capacity bet-ween the three said chambers is to cause the cold water to be gradually batted in its circular course from the outer chamber 6 to its hottest course throughout the inner chamber 9, fro-1n whence the greatest volume of hot water is had for dis charging through the nozzle 70.

By reason of the fact that the walls (Z, (Z, (Z are arranged in close proximity to each other, the water, as it circulates through the cylindrical chambers e, f, and g, is in the form of an elongated thin sheet or film and will become quickly heated by the flame from the burner in.

Air vents e, 0 are provided in the rear end 0 of the heater, in order to obtain a draft through the latter.

In the construct-ion of the device the cylinder and its integral parts are preferably of copper, in order to increase the heating capacity of the water and at the same time afford lightness to the device.

hile I have described the preferred details of construction of the features of the invention, yet it is obvious that changes may be made in the details and essential features of my invention be retained.

hat I claim and desire to secure by Letters-Patent, is:

1. In a portable water heater, a horizontal cylinder provided with a plurality of concentric water chambers in open communication with each other, an inlet pipe communicating with the outer chamber and said pipe curved upwardly and terminating with an outwardly extending flange, a discharge pipe communicating with the inner chamber and curved downwardly from the outside of said cylinder, a coupling designed to be attached to a cold water faucet and provided with a water passage in open communication with the inlet pipe and said coupling provided with a circular recess inclosing the flange of the first mentioned pipe, and a bracket made fast on said cylinder and designed to support a burner to discharge its flame centrally within the heater.

2. A device of the character described comprising a series of elongated annular water-chambers having the side walls in close proximity to each other, an inlet and an outlet in the side of said water-chamber, a cent all heating chamber surrounded by the inner wall of the innermost water-chamher and a heating device extending into said innermost heating chamber.

3. A device of the character described comprising a. series of elongated annular waterchambers having the side walls in close proximity to each other and provided with end portions, an inlet and an outlet in the annular sides thereof, a cross partition extending longitudinally between said ends and located adjacent said outlet, and a central heating chamber surrounded by the inner wall of said water-chamber.

t. In a device of the character described, the combination, with an elongated cylinder, of a series of cylindrical walls arranged concentrically in said cylinder to form a plurality of water-chambers in open communication with each other, an inlet-pipe connected to the outer wall of the outer water-chamber, an outlet pipe connected to the outer wall of the inner water-chamber and extending through the other waterchambers and through the outer wall of said outer water-chamber, and a central heating chamber surrounded by the inner wall of the inner waterch amber.

5. In a device of the character described, the combination with an elongated cylinder, of a series of annular water-chambers arranged therein and separated from each other by a single cylindrical wall, an opening in each of said walls, an inlet-pipe connected to the outer water chamber, an outlet pipe connected to the inner water-chamber and extending through all the other water-chambers to the exterior of the cylinder, and a central heating chamber surrounding the inner water-chamber.

6. In a device of the character described, an elongated cylinder provided with a plurality of concentric water chambers, each chamber being divided by a common wall and each chamber being in open communication with each other, said cylinder being provided with a central gas heating space, an inlet pipe in the outer annular wall of said cylinder, an outlet pipe extending from the inner water chamber, a swivel coupling secured to the free end of the inlet pipe constructed and adapted to be removably attached to a faucet and to permit the swinging of the cylinder to any desired position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
